What is energy in physics science?
Energy in physics has to do with either kinetic or potential "work". The ability of something to move. Motion is caused by the vibration of atoms. If the atoms were not moving (ie. at absolute zero), then there would be no kinetic energy by the highest potential energy. If the atoms (or more exactly, particles) were moving close to the speed of light, the kinetic energy would be at the highest point and potential energy at the lowest point.
What are the two types of mechanical energy?
Potential energy and kinetic energy. mechanical energy is the energy of motion(kinetic energy)or the potential of motion(potential energy) so i would say-kinetic and potential energy
What is an object with a lot of kinetic energy in its molecules?
The kinetic energy is the energ due to flow now we cannot find any objects kinetic energy and get the one which is highest because the potential energy of the object determines its kinetic value . The problem is that potential energy varies a lot and therefore you cannot determine a particular objects kinetic energy.
What is the average of kinetic energy?
Eg=3(kT)/2, where k=Boltzmann constant and T = temperature.
If you could measure the average kinetic energy of all the particles in a baseball what would you know about the baseball?
You would know the temperature of the baseball.
How does the addition of heat to a liquid affect its average kinetic energy?
It would increase its average kinetic energy which would be apparent by an increase in temperature.
What is the energy of a playground swing at its highest point?
As the swing moves, potential energy changes into kinetic energy. At the highest position all energy is gravitational potential energy as the swing has stopped at its highest position. Then the energy is converted back to kinetic energy, KE as it descends.
Why is average kinetic energy used when discussing the kinetic energy of a collection of particles?
Because the kinetic energy of many particles vary and would be normally distributed, so you could safely use an average number.
If all were at the same temperature how would the average kinetic energy of the particles compare an iron cube an aluminum cube and a balloon filled with helium gas?
If the two metals are at the same temperature then the atoms in each would have the same average kinetic energy. Temperature is a measure of the "average energy per degree of freedom". To simplify things somewhat, kinetic energy is one of these degrees of freedom and so if they have the same temperature they have the same kinetic energy. Go to the related link below for a fuller understanding of the connection between kinetic energy and temperature.

What physical factors does the average kinetic energy of molecules depend on?
Correct. But I would add, this is not just a characteristic of liquids. Temperature is the average kinetic energy of the particles in any given substance, for all states of matter.
What would always lead to an increase in the average kinetic energy of a gas?
Heating it.
What atoms of gas would have the greatest velocity if each atom had the same kinetic energy?
Hydrogen gas has the lowest mass out of ammonia, bromine, hydrogen and chlorine, so it would have the highest velocity for a given kinetic energy.
What would be the kinetic energy of particles of gas when it compressed in a cylinder?
When a gas is compressed, its temperature tends to increase. That means that the average kinetic energy per particle also increases.
What is energy associated with motion?
The energy associated with motion would be kinetic energy
What is the byproduct of energy transformation?
the answer is kinetic energy because with out kinetic energy, energy transformations would not be possible
What happens to the kinetic energy of a substance while undergoing a phase change?
It depends on what phase change they are undergoing. If it were going from a solid to a liquid, then the kinetic energy would be greater. Same as if it were going from a liquid to a gas. However, if it were going from a liquid to a solid (or a gas to a liquid), then the kinetic energy would decrease.
